Since 4-5 months i m facing problem of net, in my mobile data is not working but wifi is working properly and i changed so many sim and trying different different company sim but i m facing same problem with lenovo launcher. Lenovo service center in rdc rajnagar they update my software 14-15 times but i receiving same problem every time.in 2 days they update software 4-5 times (I. E. Yesterday, today) but no resolution received to me. When ever i go to service center they always say that from now you will not receive the problem and they failed every time.
